Tapestry Bayeux 2.0.0 released - Improved download an image streaming functionality

I have just released the final version of Tapestry Bayeux 2.0.0.

Maven:
As with 2.0.0-beta2 the new 2.0.0 will be available from ibiblio in a couple of days.

Then you will be able to depend on Bayeux by adding the following dependency snippet to your pom.xml

<dependency>
 <groupId>com.nordija.tapestry.bayeux</groupId>
 <artifactId>tapestry-bayeux</artifactId>
 <version>2.0.0</version>
</dependency>

Tapestry version:
The last version 2.0.0-snapshot was compiled and tested against Tapestry 4.1, but because of some issues with Tapestry 4.1 and Java 1.4 I decided to upgrade to Tapestry 4.1.1.

New Features:
A few extra features has been added since 2.0.0 beta-2:

• StreamLink: A updated an renamed version of the DownloadLink. This StreamLink works together with the StreamService to get access to a StreamResource defined by the user.
  The StreamService is capable of streaming all kinds of data, hence the StreamLink is useful when a tapestry application is to provide some kind of download facility.
  
• StreamAsset: As the StreamLink this asset works together with the StreamService. The StreamAsset is useful for streaming images that is not a static asset.
  That could be streaming of a JFreeChart (something that Bayeux provides special StreamResource implementations for)
• RequiredValidationDelegate: A simple extension of the default ValidationDelegate provided by tapestry. The RequiredValidationDelegate uses css instead of hard coded font color values.
  But the most nifty feature is the integration with the input fields and any associated RequiredValidator. Every input field with an requiredvalidator is marked with a *, hence you don't have to keep your required fields in sync with your validators.
  

Enjoy!

Tapestry Bayeux 2.0.0-beta2 available from ibiblio

Tapestry Bayeux 2.0.0-beta2 (binary and sources) is now available from the central maven repository.

To use the component library just add the following dependency to your pom.xml:

<dependency>
  <groupId>com.nordija.tapestry.bayeux</groupId>
  <artifactId>tapestry-bayeux</artifactId>
  <version>2.0.0-beta2</version>
</dependency>

2.0.0-beta2 is targetting tapestry 4.1 but because of an issue with tapestry 4.1 and java 1.4 I have mentioned before, the final release of 2.0.0 will target tapestry 4.1.1.

Tapestry Bayeux 2.0.0 is also intended to have some asset or component that integrate with JFreeChart - making it easier to stream charts.

Tapestry 4.1 jdk issues - fixed in 4.1.1

Lately I have spend some time investigating a Tapestry and Java 1.4 issue.
It evolved into a jira issue and yesterday Jesse Kuhnert closed the jira as the issue is fixed in 4.1.2-snapshot.
Actually it is already fixed in 4.1.1 as I tried my little testcase against 4.1.1 this morning.

Discovering this will most likely result in Bayeux targeting tapestry 4.1.1 in the final 2.0.0 release comming up.

Also I hope the changes report will tell that the issue has been fixed when a new site is updated. At the current time of writing the changes report states that the 4.1.1 is unreleased although the binary can be downloaded from the central maven repository.

Bayeux is now tapestry 4.1 compatible

I am a developer of Tapestry Bayeux and is proud to announce the release of Tapestry Bayeux 2.0.0-beta-2 (see: changelog).

The reason why I have decided to name the release beta-2 is because the flow component available in bayeux 1.4.0 isn't included in this release. But that is the only reason and the rest of the components is stable.

What is bayeux?
Tapestry Bayeux is a open source component library for Tapestry and was released for the first time back in 2004.

Bayeux contains various components primarily developed for use in projects that Nordija is involved in. But since our first release we have had numerous downloads and we know for sure that tapestry jumpstart 1.2 uses the "do it once" components.

Actually it was Geoff Callender - the developer of tapestry jumpstart - that inspired me to upgrade tapestry bayeux.

When we first released Bayeux, tapestry 3.0 had only been stable for about half a year.
Since then tapestry has evolved rapidly and the latest stable release at the current time of writing is 4.1.1.
In hope to fit as many active tapestry projects as possible, we have upgraded Bayeux to tapestry 4.1.
